J. w. w. HOLDEN THREADING DEVICE Filed March 4, 1951 INVENTOR.

AfToRmc Patented June 21, 1932 JOHN W. W. HOLDEN, OF PRQVIDENCE, ISLAND p THREADING DEVICE Application filed March 4 thread, and he extremity of the breaded end knotted to an ntermediate portion or to the end of the unthreaded portion. As a result the double thickness of the flexible member doubly distended any fabric through which it passed. In restringing beads or on naments also the hread passages therethrough were cloggec by the thread, particuwhen the neecle required o be passed through the passages a second time in an opposite direction. In both uses the presence of intermediate knots upon the flexible element made same unsatisfactory or impossible.

The essential objects of my invention are =to overcome the above detailed disadvanta es; to insure the passage of my device through an opening of minimum diameter; to insure that the flexible member be of no greater diameter at the needle eye than elsewhere throughout its length; to completel 1 conceal the needle eye and insure a secure engagement of the eye with the cord; and to attain these ends in structure capable of construction and assemblage by a quick, simple, and cheap process.

To the above ends primarily my invention consists in such parts, and in such combinations of parts as fall witain the scope of the appended claim In the accompanying drawing which forms a part of this specification,

point or the needle 'shaft blunt, orfmore pointed,

The thread or cord 15 employed with the described needle is lycircular, and throughout diametrically substantia'l-' 'its length its composed of a plurality of textile strands or filaments 16 of cotton, silk, rayon, or the like,

interengaged by means the cord 15 is engaged 10.

A convenient method and attaching the be described in con braiding. By the same with the needle of forming thecord cord and needle will now junction with the showing in Figure 3, which is purely diagrammatic, throughout. Herein 19 represents the usual intersecting sinuo plate 21 of a braid structlon with the us raceways in the top mg machine of usual conhraider bobbins moved by their carriers as commonly in the raceways. The needle 10 is firmly positioned vertically above the plate 21.

Each of a plurality of filaments 16, preferably nine in number or multiples of nine, has one end extending from a filled bobbin, through the needle eye 11, to

an opposite empty bobbins in their fa ways twists the fila bobbin. The travel of the miliarly intersecting racements into loops 27 snugly engaging and concealing the eye 11, and continue to form longitudinally disposed laterally interengaging braids 28 constituting the completed cord.

5 During the described braiding movement of the strands there is a contemporaneous downward pull and twist thereof upon the pliable needle eye or loop 11 whereby the latter is downwardly elongated, as shown in Figure 3, thereby diminishing the otherwise excessive diameter of the upper end of'the cord, which is not desirable.

It will be observed that not only is the needle eye wholly concealed in the cord 15, but

15 that the diameter of the portion of the latter embracing the eye is no greater than elsewhere; also, that the braided interengagement of the filaments with the needle eye and with each other insure such a secure attacha0 ment of the needle with the cord as to pre vent severance under a maximum strain.

I claim 1. In a device of the character described, a metallic needle comprising a shaft and a ter- 95 minal loop, and a cord .comprising braids fixed at their ends to the loop, the cord being of greater cross section than the needle.

2. In a device of the character described, a needle comprising'a shank and a loop, and a cord comprising a plurality of filaments interbraided withand embracing the loop.

3. In a device of the character described, a metallic needle comprising a shank and a terminal loop, and a cord comprising textile fila- 5 ments braided to the loop and enclosing the same. r

Y 4. In a device of the character described, a

metallic needle comprising a flexible shaft and a flexible loop, and a cord comprising in- 9 terengaged braids terminating looped portions passing through the terminal loopand concealing the same.

In testimony whereof I have aflixed my signature.
